To all whom it m 013 crmccrn Be it known l; .z-in'rmin h I zen of the United State siding at We? lingtou, in the county V of c oilingsworth and Slate of TGIMS, have invented new and useful improvements in i iutoinutic Liquidl ucl Regulators for t ini ilcnei'stors, of which tilt-following u ruieeification.

This invention is on improved automatic liquid fuel feed regulator for steam generotors especially adopted for use in connection with steam generators in which liquid hydrooerhon or nos is used as fuel, the object of the invention being to provide on in); proved mechanism of this kind which 'h'en properly adjusted will on A ulate the supply oi. liquid "Fuel to the. hi'arners of the furnace oecordi to the pressure of the sl'onni. in the hoilei. and thus serve to automatically it p the strain u pres sure desired and prevent the waste 0}, fuel and :ilso prevent an iusuilicient quantity ott fuel from being supplied to the furnace.

The invention consists in the cmisl'ruction, combination and nrinngonient of devices hereinafter described and claimed.

in the eccon'ipunyinp; druwiupsz Figure 1 is an elevation of :1 liquid fuel feed rcgulm tor constructed in accordance with "my invention, showing the some arranged in operative relation to u sicom boiler and its rim-mice. Fig. 2 is 21 do. iii elevzniou oi? the iinprm'ed automatic liquid fuel feed TQIfllltor. on, u larger scale. and with the cylinder of the steam pressure actuated mechanism in section. Fig. 3 is u detail transverse sectional View on the plane indicated by the line a-e of Fig. 2. Fig. 4 is ti-detail horizontal sectional View of the rocker segment on the plane indicatedby the line b-b of Fig. 2 and showing the valve actuated lever in plan.

For the purposes of this specification, 1 show in Fig. 1 of the drawings a steam boiler at 1, its furnace {Lt 2 and a tank or reservoir for liquid hydrocarbon for use es fuel to be burned by the burners of the furnace at 3. Wh ere the invention is for use in connection With a furnace in which gas is hurnedns a fuel, the reservoir 3 will he replaced by a suitable gas hell or a supply pi e leading from an ordinary gas system Wil be utilized.

In accordance with my invention 1 "pro vide the fuel supply pipe 4, which leads from the source of liquid hydrocarbon or is provided ml or suiiiohle (ml? to the steam space of lhe UTE, F0333, v 'EQLLIDllBl-TOLQ",

'ch engage the threaded stems, bear on the upper side 01'? the 9 plate 1"? and enable the letter to he i adjusted, as will he understood. .P spring 19 is also prwided. which. shown as a coiled exten 'ile spring A around the piston rod 520 which exte: o. Wardly from the piston, the lower on the said spring bearing on the nist upper end'hearing against tl -11 L the bar or plate 1'4". This spring! I counteract the pressure of steam inder below the piston.

The piston rod. 20 operates in on. in the center of the or f e l" connected by a rod the rocker segment 12 pivotally attached to the piston rod and also to the rocker segment The tension of the counteracting spring 19 may be varied by adjusting the plate or bar 17 according to the desired. pressure in the boiler and the valve actuating lever should be adjusted appropr ately to the rocker segment.

In the operation of my improved fuel feed regulator the valve 5 is open until the desired pressure of steam in the boiler is obtained, the counteracting spring 19 serving to depress the piston 15 and to hold the lat ter in depressed position in the cylinder. When, however, the pressure of steam in the boiler exceeds that desired, the piston 15 is moved upwardly in the cylinder 13 against the tension of the spring 19, thus causing the rocker segment to be partly turned and the valve actuating lever to move correspondingly with thefrocker segment and, hence, partially close the valve 5 to the required extent to so diminish the supply of liquid fuel to the burners as to prevent steam from being generated at excess pressure. As soon as the steam pressure becomes reduced, the counteracting spring 19 will correspondingly depress the piston 15 and thus cause the regulating valve 5 to be more widely opened and thus supply an increased quantity of fuel to the burners in the furnace. Hence, my liquid fuel feed mechanism is automatically operated and controlled by the steam pressure in the boiler and by the coaction of the counteracting spring, excess steam pressure in the boiler is avoided and an economy of fuel effected.

While I have herein shown and described a preferred form of my invention, I would have it understood that changes may be made in the form, proportion and construction of the several parts'without departing from the spirit of the invention and within thescope of the appended claim.

I claim In combination with a steam generator acting spring to move the-piston in the reverse direction, a rod projecting from the piston and a pitman ivotally connected to the rocker element and to the piston rod.

In testimony whereof I afiix my signature in presence of two witnesses.
